CVSS: 5.3EPSS: 14%CPEs: 42EXPL: 0CVE-2021-33037 – Incorrect Transfer-Encoding handling with HTTP/1.0
https://notcve.org/view.php?id=CVE-2021-33037
Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP transfer-encoding request header in some circumstances leading to the possibility to request smuggling when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding; and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding. Apache Tomcat versiones 10.0.0-M1 hasta 10.0.6, versiones 9.0.0.M1 hasta 9.0.46 y versiones 8.5.0 hasta 8.5.66, no analizaban correctamente el encabezado de petición HTTP transfer-encoding en algunas circunstancias, conllevando a la posibilidad de contrabando de peticiones cuando se usaba con un proxy inverso. Específicamente: - Tomcat ignoraba incorrectamente el encabezado de codificación de transferencia si el cliente declaraba que sólo aceptaría una respuesta HTTP/1.0; - Tomcat honraba la codificación de identificación; y - Tomcat no se aseguraba de que, si estaba presente, la codificación en trozos fuera la codificación final • https://kc.mcafee.com/corporate/index?page=content&id=SB10366 https://lists.apache.org/thread.html/r290aee55b72811fd19e75ac80f6143716c079170c5671b96932ed44b%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r40f921575aee8d7d34e53182f862c45cbb8f3d898c9d4e865c2ec262%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r612a79269b0d5e5780c62dfd34286a8037232fec0bc6f1a7e60c9381%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/rc6ef52453bb996a98cb45442871a1db56b7c349939e45d829bf9ae37%40%3Ccommits.tomee.apache.org%3E https:/ • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 5.8EPSS: 0%CPEs: 136EXPL: 1CVE-2021-29425 – Possible limited path traversal vulnerabily in Apache Commons IO
https://notcve.org/view.php?id=CVE-2021-29425
In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value. En Apache Commons IO versiones anteriores a 2.7, Cuando se invoca el método FileNameUtils.normalize con una cadena de entrada inapropiada, como "//../foo" o "\\..\ foo", el resultado sería el mismo valor, por lo que posiblemente proporcionar acceso a archivos en el directorio principal, pero no más arriba (por lo tanto, salto de ruta "limited"), si el código de llamada usara el resultado para construir un valor de ruta • https://issues.apache.org/jira/browse/IO-556 https://lists.apache.org/thread.html/r01b4a1fcdf3311c936ce33d75a9398b6c255f00c1a2f312ac21effe1%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r0bfa8f7921abdfae788b1f076a12f73a92c93cc0a6e1083bce0027c5%40%3Cnotifications.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r0d73e2071d1f1afe1a15da14c5b6feb2cf17e3871168d5a3c8451436%40%3Ccommits.pulsar.apache.org%3E https://lists.apache.org/thread.html/r1c2f4683c35696cf6f863e3c107e37ec41305b1930dd40c17260de71%40%3Ccommits.pulsar.apache.org%3E https:/ • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to occupy a thread that consumes maximum CPU time and will never return. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.
